    My Ultra CDP II is outstanding in reliability and accuracy. I just acquired a chronograph, so I'll post some velocity comparisons with my 5" Desert Warrior before long. I am, however, totally confident that the Ultra will get the job done.

    Ti Carry, if you can pocket carry a snubby, you can pocket carry an Ultra Carry II. However, tight pants just won't cut it. I carry mine in jeans, casual and dress trousers.

    Yea, I don't wear tight so much but one's that fit me with an IWB holster so about 1 size larger. My leg's are thick from years of water sking and working out. So finding pants (other than 5.11's to wear everyday) is hard to find with leg's with enough room to not tighten up when sitting down thus my carry piece buldging through.

    Not a big deal, I guess we all can't be the same and carry any way we please.

    If you have a concern about the ability of the 45 ACP round to expand when launched out of a three inch tube i would have to assume your talking about a 230 gr. standard pressure load. Maybe thats got truth to it, I dont know. Try a 165 gr JHP load or the 185 gr+P JHP load. This should tighten ya up.

    I bought a use S&W 4513 tsw and have not had any failures in about
    300 rounds. It has a 3 3/4" barrel and at 15 yards is pretty accurate.

    As stated i would not want to be in front of it.

    If talking about the a 1911, I have read some posting on the m1911.org forum that less then 230 gr rounds may affect reliability in 3.5 inch and smaller barrels.

    I look at it this way, I carry 230 JHP. If it expands great, if not well it is still making a .45 inch hole.

    With my Ultra Carry, I am more than confident in it's performance.

    I've never had one single hiccup in over 1500 rounds ~ ball, JHP, or otherwise.

    i carry (and recommend) lighter loads in shorter barrels to increase velocity.

    Geesh,

    You guys are all 1911 platformers? No glocks amongst you, at least from the responses so far.

    My g36 may lose some velocity [ 3.75" barrel ], but it gains some of that velocity back being a polygonal bore and tighter sealing than lands and grooves.

    I use the 230+p Win Ranger in the shorter g36, between that and the polygonal, it loses nothing over standard vel to my 5 inch gov. models.

    Pocket carry? Sure, the g36 regularly sits in the back pocket of the jeans. I can't see carrying in the front pocket of the jeans, too tight and almost impossible to get too while seated.
