    Series 70 steel Commander and self defense 185Gr. +P ammo

    Is +P ammo ok in this gun? Just enough rounds down range to check feeding reliability.

    Should be okay.

    Due to the hotter ammo you might consider experimenting with a stronger recoil spring.
    The stock spring is a 20 pound spring.
    For hotter ammo you might try a 22 pound spring.

    Note that you MUST experiment with enough rounds to insure reliable operation.
    For practice ONLY you can also install a buffer pad, but for actual defense use NEVER leave a buffer in the gun.
    These polymer buffers do wear and start coming apart and the pieces can cause a stoppage.

    Buffers aren't recommended for Commanders...whether aluminum or steel framed. Even Wilson Combat states that. For the shorter recoil stroke it's a malfunction waiting to happen.

    Personally I don't see the point of +P ammunition for the .45 ACP. I don't think the added recoil is worth it. If you want to try a standard pressure .45 that acts like it's on steroids...try Winchester's 185 grain SilverTips...THAT will make you believe it's +P! It like miniature hand grenades going off each time you squeeze on off.

    I've found that a heavier recoil spring makes the pistol work harder. I put extra pound recoil springs in my Commanders and the felt reoil was harsher. Basic physics.

    Isn't that silver tip what they call a flying ash tray?

    'Flying Ashtray' - 'Flying Coffee Cup' - the effect is much the same...

    A stronger spring WILL keep the slide from slamming the Frame caused by the hotter rounds FYI ..

    I emailed Wolff and asked them about buffers. They replied: "a properly sprung semi-auto does not need a buffer" Well, OK, but how do you account for different loads? Anyway, have some Dykem (aka Prussian) blue? Clean the frame and slide and put a thin coat on the rear edge of the dust shield. If the blue transfers after firing a mag or two, you have slide-frame contact. Go up 2lbs on the spring rating until that stops. This is with a given load, mind you. Wolff sells a "calibration pack" for 1911s and (Combat) Commanders that is the most economical way of doing this.

    Silvertip is Winchester , the "Flying Ashtray" was an 185 gr Speer bullet that is no longer made I am told . I have several hundred loaded rounds using this bullet that would be I think in the +P range . That and GI hardball are all I shoot in my Gov model 70 series . I see no reason to think you would have any issue shooting +P in a Steel frame Commander . I probably have at least 10000 rounds of +P level ammo through my Gov model and the only thing that has ever broke on it was an extended thumb safety lever and the elevation screw in the Meprolite night sight .

    I always was under the impression the "Flying Ashtray" was the Speer 200 grain JHP...it had or still has a short bullet with a large, gaping opening and had a reputation for not giving reliable feeding in many pistols unless they were fully throated. That also comes from before the days before Colt started throating their pistols as much as they do now...the problem was probably limited to pistols with the GI-type throating for hardball ammunition only.

    I've got a box of it stored away...never have tried it. Bullet technology has improved a great deal since it was considered the round to have...lots of excellent choices to pick from now.
