I wouldn't say they are brutal. The 45acp round isn't a very high case pressure round. I find a Glock in .357 Sig, much more snappy and unpleasant to shoot even in a full size model. Full power 10mm ammo also packs a good bit of snap and recoil. The thing is.......if you shoot often you get used to it. Normally any typical carry gun ammo isn't going to "hurt" you. If recoil is bothersome, lighter ammo is usually available. If recoil is that bad, it's not a good defense gun. There's more ammo variations available in 45acp than any other round including some that are advertised as "Low Recoil"
I couldn't agree more, I also found the 40 S & W had more snap then a std. load .45. The "hot-fast" rounds seem to have a little more snap to them
Can I play too?
Kimber Custom shop Eclipse target 1911 .45
Kimber Custom CDP 1911 .45 (main carry gun in a Milt Sparks VS II)
Glock 17 9mm Customized. (more about this recent acquisition later)
Bushmaster M4 .223 (I'm about to convert this to a flat top with a Trijicon 3x, and I just bought front rail mount hand-guards and a Surefire light, more about this one later too)
FL, As far as holding up a holster, have you tried a Wilderness Tactical belt? They REALLY work.

Pics in a few days, it's on the way to my FFL bud. My wife has the single stack version, we'll be like bookends
