Depends on where you live , we don't have the humidity here in Arizona but we sure have the heat. won't comment on humidity but the heat can and will definitely affect ammo, seen ammo breathe and smell while stored in old military ammo cans left in metal bldg's in the sun.  Generally most people here keep ammo in the house or garage or insulated cool place.  Wouldn't be a bad idea to have an under or above ground ammo bunker covered with dirt  and shade trees for insulation to keep it cool. At least here I can't leave ammo out sitting on the tailgate or any other place open to the summer sun ammo just gets too hot even to touch sometimes   I have to keep it in the shade as much as possible.  I do like to test loads when at or near max charge weights  when it's pretty warm out.  I've stuck enough bolt's thru the years to know heat and powder don't mix real well.  As temperature insensitivity as some of these newer powders are suppose to be imo there is a limit on just how hot you can get this stuff and be practical.  I keep my ammo covered out of the sun as much as possible.  I've melted plastic camera in the back seat, bic lighter explode on the dash , melted all of one of our boats plastic  electric panel switches  get soft and deform luckily our other boat has old school metal switches just can't touch them in the summer sun,  so we carry beach towels to lay on the vehicle  and boat  vinyl seats.  we literally have to crack the windows open a little in the vehicles when it's that hot.  luckily I will be hunting down in the Superstition mtn's and wilderness on Coues White tail hunt in Nov so the heat won't be a problem, rough ass country long shots are probable.  will be using a little Vanguard synthetic in 6.5 creedmoor  with first focal plane Nikon 4x16.

Putting in for spring Turkey on the north rim of the Grand Canyon,  hopefully I can get drawn, the plan is to take the wife up on a scenic  side by side drive around and look at all the northern points looking down on the canyon. getting older probably get a motel in Kanab Utah and short drive into AZ.  We have been up on the north Kaibab and strip  deer hunting several times always something interesting to see,  will stop in at Muley Crazy (the magazine) in Kanab and look at all the trophy deer  mounts, we try to stop in and visit  and get good info. 

It's going to be real nice. 

There is no way I will buy an electric or hybred vehicle period.  we don't have the infrastructure, we don't have the batteries, we don't have the technology yet to make it viable, you can't tow with them for any distance before charging and where are you going to charge your vehicle in the sticks or bad weather conditions , are you going to call triple  A  to get a tow when you should have known better,  oh yea it's going to be cheaper,  say's who ?    What are you going to do without semi tractors, farming equipment, ships at sea, airplanes,  power plants,  emergency generators for hospitals and institutions,  chain saws , snow blowers,  you name it.  These people need to move to mars.  a hundred years from now maybe they will invent  alternatives, but right I don't know where the common sense went.

I don't know anything about the Savage 1911's ,  they may very well be worth the money.  For a no frills 1911 rock island armory (armscor)  go bang,  there are some old LLama's out there that aren't bad guns they are not exactly the same,  Ruger makes a decent 1911 when my son in law was  at university he interned over the summers for Ruger they have a couple.  Kimber makes a good 1911 as does Sig, you may want an original Colt even if it's used in good condition ?  It's really hard to beat an older series 70 gold cup in 45acp a little pricy in very good condition,  you can look around. Question  series 70 or series 80 ?  FULL SIZE or COMPACT gun ,  mil-spec or not mil-spec ?  custom or stock ?  do you prefer an arched main spring housing 1911-A1 or the flat main spring housing of the WW1 style 1911's handle them both and see which one fit's you,  I have both and prefer the flat style.  the main spring housing can be switched out for the most part.    Not all magazines will fit all 1911's even of the same frame size.    Remember the newer the 1911's  can generally feed most decent correct nose profile bullets/ammo,  the same can't be said for old 1911's or A-1's that were made for military ball ammo,  hence older 1911's getting ramped/polished, tightened, accurized, etc.  the cool thing about 1911's in general is the amazing amount of aftermarket parts to enhance the overall gun to suit your personal preference.  Of the non mil-spec magazines other than whatever came with the gun,  Chip McCormick shooting star magazines fit in my colts and  are very well known to top  1911 shooters.  Mec-gar makes  good magazines,  if your gun can use military issue  mil-spec mags find them at the swap meets, gun show's , gun broker, etc,   get a bunch of magazines  5 to 10 at least down the road and rat hole them,  I had all the  bases on my shooting star magazines tig welded and of course shooting star mags comes with their own followers which are really good.   The reason we had the bases welded we were shooting matches where you had to drop the magazines sometimes with a couple rounds of ammo still in them and when hitting the ground the bases came loose and ammo and spring went all over.,  hence why we welded them,  we didn't worry about the bottom welds the shooting star followers of this style come out the top so you can clean the mags if you wanted,   that was years ago but still holds true.   If money were no object I would have one built on a Caspian frame & slide with all the goodies,  adjustable Bomar or equiv sights,  have a Bomar cut milled into the slide.  fine line checkering in both front and rear straps, slightly beveled mag well nothing goudy,  extended mag release, full length guide rod with poly shock buffs,  have the trigger gone thru  NO slop nice and crisp.  I'd buy a bunch of Wilson recoil springs of different weights to play with different intensity  hot to mild loads.   But that's just me.  Read up on the differences and warnings between the series 70's and series 80's guns,  if they are an odd ball gun with differences from the original Colts then read up on ALL the safety features or lack thereof  before making any decisions.  These gov'n models are professionals guns it's not like picking up a Glock.   You shoot a match trigger 1911  that shoots 1 1/2 @ 50 yds you will wonder why they even came out with these new striker fired triggers not even a comparison. 

IMO if you are going to have a FULL  SIZE 1911 get it in 45 acp or 10mm ,  or even a 38 super which is a very cool caliber by the way,   leave the 9mm to other  smaller guns.  yes you can shoot faster with a 9mm, but it ain't no 45acp or 10mm either.

leather is quiet, it's comfortable as long as it fits you right,  I think it looks better.   I do have a few kydex holsters and I will use them on occasion where I may need the holster to keep it's shape a little better while re-holstering and that's more of a case for IWB holsters.  I can and do make my own holsters every now and then more so for some special use,  plus  perfect gun and body fit.  These are hand stitched or double loop laced.  I do like high quality LINED  leather holsters and high quality double thickness glued and stitched  leather gun  belts usually  1 1/2 ".  once you wear it for awhile and get the new feel and stiffness out they are a good as they get imo,  they are well worth the hundred + bucks as long as you don't grow too much and have to pass it down to your wife or kids, then they grow too much and have to pass it down to the grand kids.

Our old friend Roger (terminator)  use to carry a little 7 oz Kel-Tec P32 , 32 acp in his pocket,  I really wouldn't mind having one,  there are times when wearing summer clothes (shorts) that little lightweight pistol would sure be comfortable.  Yea it's a last ditch effort and that's what it's made for.  There a couple other guns out there that would fit the bill imo, something like a little NAA revolver in 22 mag,   maybe get a spare cylinder just in case. 

I've said this for how long ,  stock up on things, doesn't really matter what it is as long it's something people have to have,  use it for trade and barter if you have to when it hits the fan.  you don't have to go insane on the amounts of the stuff you stock up on just enough you think you will need in bad times.  This is where farmers really have an advantage.
