Hey all- My previous thread on Springfield got me to wondering: What makes one 1911 more accurate than another? Is it barrel to slide lockup? Slide to frame fit? Barrel bushing? I plan on keeping my Sig 1911 as a workhorse while the TRP will be part BBQ gun and part "when it counts" gun. What can I do to enhance the performance of the Sig? Things I have already done: Sent back to Sig Custom Shop for a trigger job and feed ramp polish. I also had a Les Baer "gas pedal" ambidextrous safety fitted. The slide to frame fit is not tight but it doesn't rattle. No movement of the barrel when I press down on it, when locked up. What about having a tightly fitted barrel bushing done? That seems like a cheap and easy upgrade but does it help? Or is this gun as good as it is likely to ever be and I should just get on with trying to wear it out ?

IMO barrel to slide, bushing to barrel, bushing to slide, bottom lugs to slide stop pin, and trigger will have the most impact. Assuming a quality barrel and crown. --------------------------- My hovercraft is full of eels. | |||

It sounds like the only currently alterable factor there is the bushing, correct? Bruce "The designer of the gun had clearly not been instructed to beat about the bush.

The separate barrel bushing on the 1911 is part of the barrel/slide lockup. It can be made tighter both inside the slide and around the barrel. Too tight may cost reliability. If you didn't need a barrel bushing wrench before, you will after. But you can strip and clean the gun at your leisure, not in a trench or jungle. | |||

I don't want to come off as a dick, because (i) that's not my way; (ii) I don't know you; and (iii) I'm speaking from personal experience: BUT... I'd wait until I had the TRP in hand, shoot the SIG and TRP side by side, and get a better idea if it the gun, the sights or the shooter. I say this because I have a full size Springfield 1911 that was modified by a prior owner to have a Wilson barrel bushing and Millet target sights. I also have a 4.2 inch SIG GSR Revolution Carry. I shoot the SIG better, mostly because for me, it has superior sights. I don't think that it is an inherently more accurate gun. So my suggestion is, that before you send the SIG off for work, shoot them side by side and get some comparison data. That may help you decide if, and what you want to do. Congratulations on the new pistol. I'm looking forward to pictures. "I vowed to myself to fight against evil more completely and more wholeheartedly than I ever did before. . . .

Barrel link and pin, can affect accuracy and reliability. Far Less on accuracy than other things like a too-loose barrel bushing, but can negatively affect it if it's too far off. Link/pin generally affect timing/reliability more. Basically, if the link and pin are the right size, it won't affect accuracy, but if very wrong, can "detract" from intrinsic accuracy. | |||

Good suggestion, which I plan on following  (You are not a dick, BTW)I posted now because I am wondering about it now. No credit card smoking or gunsmith booking plans, presently. Thanks!

Very wise! What hurts the accuracy of my 1911s most is me. "I vowed to myself to fight against evil more completely and more wholeheartedly than I ever did before. . . .

I'm old, with that said I go back to MCRD Parris Island SC 1964 familiarization firing of the 1911A1. Since that time I've in jest stated that I've fired enough 45ACP rounds to fill a couple 55 gallon drums. Usually the greatest improvement in accuracy is the competency of the shooter followed by accuracy enhancement procedures. | |||

Agreed. I will likely not be able to reliably or consistently display the difference between a 1.5" gun and a 2.5" gun. My shooting is not good enough and needs to get better. I just like machines and am constantly intrigued by the difference between the blueprint and the end product. Ayn Rand said "A machine is a thought, given material form" or words to that effect. Stacking tolerances irritate me. Getting rid of them, I feel, honors the intent of the geniuses that made the blueprint. So, I tinker or ask others to tinker better than the assembly line.

There are three areas that accout for about 95% of 1911 accuracy. They are the bushing\barrel\slide interface, the barrel hood\breech face, and the slide stop pin\swing link\barrel foot interface. You can get a custom measured bushing from EGW that should both drop in and close up some of the play at the front of your gun. I did this to a Springfield 9mm 1911 and it did reduce my group size by about 40%. The slide stop pin and swing link is a little more difficult to do without some first hand knowledge. First off, what does your current pin look like? Is their even wear on both sides of the pin, ond on both of the barrel feet? How much upward force is the link exerting on the barrel when the action is cosed? And lastly, how tight is the barrel hood to breech face fit? These areas are where the mechanical accuracy comes from. A good trigger and better sights just make it easier to exploit your pistol's inherant accuracy. _____________________________ 'I'm pretty fly for a white guy'. | |||

For me, its a roll of the dice. My first full size 1911 was an old mil spec parts gun, including the tiny original sights. At 25 yards, it would put a full magazine into about 4 inches with GI ball. I sold it to a friend and replaced it with a brand new Series 70 Colt. Accuracy went to minute of paper plate at 25. There has been lots of good advice on what makes a 1911 more accurate. but I have never been able to figure out why the ugly rattletrap old parts gun out shot the brand new Series 70 Colt. My current full size 1911 carry gun is a Ruger SR1911. Factory stock and so far, 100% reliable. My best group with it at 25 is 5 inches. Thats good enough for me from a factory production gun. It might do better if I find ammo it really favors. End of Earth: 2 Miles Upper Peninsula: 4 Miles | |||
