Just out of curiosity what recoil spring poundage are the 1911 Commander 45 Auto shooters using? I am contemplating changing out my spring.
Should I change to a heavier poundage or not? If needed what poundage?
Thanks

I don't have a commander but, what is your reasoning for change?

I don't have a commander but, what is your reasoning for change? The reason is to add a dab of protection on the battering caused by the slide velocity. I am not saying it necessary since I will probably rarely if ever shoot +P ammo but what would it hurt to jump up a couple pounds? I am not talking about jumping to some level that is extreme. Just a couple pounds at most. Is it needed, probably not. Would it hurt anything though? |

Well just as long as it functions fine and does not slam too hard. Just don't forget that if you ever change ammo it may not function with it. I believe the factory spring is 16#. I did a lot of experimenting with 1911 springs back in the 80s. I always went with the one that functions fine for my loads, and felt good to me nice and smooth.

I'd grab a wolff extra power recoil calibration pack and play with it. www.gunsprings.com/COLT/COMMANDER%20SERIES%20PISTOL/cID1/mID1/dID216# is standard for government. 18# for a commander. 230 grain at about 850 fps. Hotter would want more spring, and vice versa. A small radius firing stop is a great upgrade without messing with the recoil springs. Makes the mainspring take a little more force before it lets the hammer (and therefore the slide) move. At one point I had a commander 10mm with a 26 lb recoil spring and a small radius FPS. Running hot loads it was still throwing brass 15 ft, and my wife was physically unable to rack the slide. |

Agree with Aggie, 18# is normal for Commander/45. For defensive use or hunting I’d stick with it,unless you’re shooting 800+ rounds a year it’s plenty. However keeping everything lubed properly will ensure longevity. Slide/frame rails, locking lugs, disconnector, barrel muzzle/bushing, barrel link, everywhere metal to metal contact occurs, a slippery grease does wonders.

18lbs. is standard for .45ACP Commanders. I would stay away from shock buffs in a Commander. The Commander is a short stroke gun. By that i mean that the slide does not travel as far to the rear as a Govt. Model or Offficers Model.
I am a big beliver of flat wire spring conversion in .45 ACP Commanders. Either the Nighthawk setup if you like full lenth guide rods or Wilson Combat makes a Commander flat wire guide rod and sells the flat wire springs.
The right setup will minumize frame battering and most importantly.......Be reliable!

The above suggestion of a small radius or flat bottom firing pin stop is the way to go...
In addition a heavier main spring will also delay opening and slow the slide down.. I believe stock is 23#. Brownell's has test packs that run from 20 to 28#. Have been using a 26 in guns made for 10mm and .45 Super. Both guns will run with lighter loads...
As to Shok-Buffs in a Commander, the rearward slide travel will stop right when the slide stop and notch in the slide line up. With heavy loads my .45 Commander would have the slide stop rotate right up into the notch a couple of times a magazine. Took it out and ran fine...

As rmj52 stated the flat bottom or small radius firing pin stop will make a big difference by slowing the unlocking of the gun. I believe I have put 23lb. stainless mainsprings into my guns.

I have put these on most of my 1911's, have never had any ill affects. |

***** A recoil buffer can be a good thing, especially if the gun is designed for it. OVERTRAVEL is a important concept in autoloading design, but requires adding length to receiver or shortening bolt, etc. Bolt or slide overtravel is an easy way to accommodate cycling with a wide range of loads, exemplified by the supremely reliable Heckler & Koch G3/91 .308 rifle, which bolt overtravel exceeds cartridge length. Buffers for the 1911 are a consumable, replacement dictated by wear. I’ve used Bill Wilson’s and others, and made buffers from hard leather. All cushion but should be watched. Never had buffer-related stoppage, but have heard of pieces breaking off to impede cycling. A buffer which seats on the recoil spring guide of a 1911 e shortens slide travel 1/16 or 1/8-inch. Magazine must raise cartridge fast enough for breech face to catch it----essentially without overtravel. Carried an early Colt Commander for a period. With standard spring and without recoil buffer.

Wilson Combat says they dont recommend them on anything shorter than a 5" barrel.
