Re: just got cpl, ideas on the best 45 to carry?
Congrats on your promotion.
Personally, I think that old J.M. Browning did a pretty good job with the basic M1911A1, and my choice would be something along the lines of a Series 70 Gold Cup, with the proper recoil spring weight to match the loads you'll be running. The adjustable sights and a well fitted barrel and bushing are the key to 1911 accuracy. I'd finish the package with Pachmyr Signature 1911 Government grips and add the modified grip safety with the spur that prevents hammer 'bite' (I have faint permanent scars on my hands from 'bite').
This is the basis of a 'professional' 45.
There's a difference between a race gun and a professional gun; IMHO, and the difference lies in the lockup process. Tight is good for accuracy, looser is good for reliable cycling. You need to use some judgement; but if lives are at stake, accuracy is secondary to reliability. This can be made optional by using barrel links of different lengths (longer for tighter, shorter for looser). Too light a recoil spring can damage the frame (use a buffer in any case), and make going into battery iffy. Recoil spring guide rods can look sexy, but one wonders how much time they may add to reducing a a malfunction.
Accuracy under response conditions; 6"-8" at 25yd is acceptable 'minute of jihadi'. 50yd is a long shot for a 45, but keeping nearly all of them within center mass is good shooting under pressure. Like LL says, you can't miss fast enough to win a gunfight. Slow down, acquire a real sight picture, and work the trigger responsibly. It only takes one good shot to save that life, second place is dead, make 'em count.
Full length, not Commander. Pistol barrels are short enough without pulling a 'Bobbitt' on yours.
Stainless makes carry guns less 'weary', and a stainless gun can be 'dehorned' (sharp corners knocked down, mag well slightly bevelled) without requiring a complete refinishing. If it's too shiny, use semigloss black Krylon, it comes off easy enough later.
