WildRomanian:
Thank you for your post!
Having been in the gun biz for about a decade myself, my experience has been somewhat different. Yes, a
tuned 1911 racegun will feed target wadcutters. Several semiauto target pistols of German and Italian extraction will feed rimmed .32 cal full wadcutters. Does this make them the ultimate in pistols? My ParaOrdnance P12.45 is the only NIB 1911-pattern pistol I've personally owned that was 100% reliable with all JHP ammo available right from the box with factory mags. I've seen many others that would "feed it all", but it's always been a hit or miss thing in my experience, with some round (either hot +P ammo, or lightweight bullet loads, or feed-unfriendly JHP ogives such as the CCI "Flying Ashtray" or MagTech's 185gr +P JHP) needing mag tweaks or replacement or recoil spring replacement or maybe a "ramp and throat" to solve the issue.
This used to be the norm with autopistols; having a certain round or two that the gun "just didn't like", but I've had too many modern autopistols (Glocks, P-series SIGs, full-size Berettas, HK P7's and USP's) that feed everything straight from the box, no tweaking required, at least as far as jacketed factory ammo goes, to accept the old "well, it's just fussy" from a factory gun any more.
If feeding lead wadcutter ammo loaded over mild target loads is your priority, yes the 1911 is the gun for you (after suitable mods). If feeding aggressive JHP's right out of the box in a CCW handgun that has a good chance of being ready to go with no 'smithing needed is your need, you and I know there are better choices than the 1911.
However, I
sure don't think the 1911 is "obsolete"; if I did, why would I have had a Springfield on my hip all day?
