    I've read the recoil would be less offensive in the PM.45 vs the PM.40 despite actually being a larger caliber. Is that true?

    Recoil on either one is not a problem.

    i agree, neither is a gun that you want to shoot a couple 2-3 hundred rounds through in a session. ive never shot the 45, the 40 is snappy but i would not call it punishing. follow up shots are not a problem for me.

    The fact that you are considering a PM series at all hints that size and concealability is a priority to you. To that end I'd get the PM40.

    PM40 = 5.35" Long / 4.00" tall / 0.94" thick / 15.8oz
    PM45 = 5.67" Long / 4.49" tall / 1.01" thick / 17.3oz

    IMO I would go with the PM 45. I own P45 and PM 45. I have shot the
    PM 40 and I think it has more snap than the PM 45. I can shoot many rnds out of the 45 and the 40 hurts after about 50 rnds. I have been shooting
    for more than 30 years, so recoil on most guns does not bother me. Good
    luck. 8th

    I think the PM45 is going to be more enjoyable to shoot at the range and maybe easoer to shoot accurately, but the 40 is going to be easier to conceal.

    For me, many guns have come and gone for CCW duty because they just didn't work out for concealment or ease of carry. Therefore the most important factor to me is concealment, which gives the PM40 the edge. I am also a .4 caliber guy and prefer heavy bullets. Thus the 40 beat the 9 for me.

    Your preferences may vary, so the size difference may not be as significant a factor. In a life or death situation, recoil is going to be less of an issue, but how well you shoot the weapon will be very important.

    When I started practicing with my PM40, it was strictly a close up last resort weapon, as I was not reliably accurate beyond 3yds. I have increased my effective semi-rapid fire range to 7-10yds now, but it certainly isn't a gun I would pick for home defense where my effective range needs to be 15yds. My point is that if you feel your defense scenario needs to include a longer range accuracy capability, you may want to consider a larger and possibly more controllable weapon...I.e. The PM45

    I own both. I think the PM40 with full-power ammo is snappier and less fun to shoot than the PM45. I can shoot the PM45 all day. Medium velocity .40 is much more tame and actually more reliable in my PM40, so that's what I carry. It is still a formidable cartridge in the MV loading. I don't carry 45+P in my 45's because I get faster splits with standard's just a preference thing.

    They are both very accurate. I qualify with both of them at 25 yards, and they are tack drivers. It's surprising, but true.

    The 40 does conceal better, and I carry it all the time. My 45 is having trouble with the magazine ejecting uncommanded. I'm not carrying it until I send it back for inspection.
