    I’ve been trying a 160gr. roundnose cast bullet but so far have not been able to get it to cycle the action using loads based on the155 gr. data i’ve found online. The bullet is scary accurate but i’d need to go beyond the posted data to get it to function. I’ve had great luck however with the RCBS 185 gr. cast/powder coated. I think the gap’s heavy slide makes the 155/160 gr. bullet a difficult proposition. I use Titegroup as well in my g37.

    Is here any such thing as a Gen4 G37/38/39? Glock only shows Gen3 on their site. I have heard tales of a Gen4 but never seen one anywhere, or is it an LE-specific thing?

    There is a Gen 4 G37, the G38 and G39 is limited to Gen 3.

    Are you in GA or FL? I know SC, GA, FL at one time carried the G37's. Here in SC they've gone to 17.5's. I do believe GA switched as well but I think FLHP is still rocking them.

    Seems like a straight forward, easy round to reload for any inclined. and small pistol primers!!

    I think GAP is cool, but not so hot on the limited mag cap's. In my eyes, if it is a smaller catrdige, like the size of a .40, could they not have upped the mag count? I may be mistaken here, and it is bigger than I suspect. But 10 in a full size pistol is weak in my eyes. And I do not, not, not need more crap and calibers to load for!! lol. I have never been one for the .45 though.

    picked this gem up today. Almost pristine condition. Loving the Gap round more and more.
    settled on a 185 grain Rn for my GSSF loading.

    Agree, and I have done that before but a majority will be turned off of any cartridge if it's not available NOW.

    They could have but then the grip would have been the same width (side to side) as a 29 or 30. Their goal was to have the same grip size as the 9mm, .40, and .357 models.

    I really want to try this caliber just for GSSF and a reloading experiment.

    Hello sir,i have the rcbs 201 gr. as well but i find this one feeds better. I found the mold on Midwayusa’s website. Here is a couple pics of the mold: BC09BFEC-13F0-4081-B995-A3DD18EB73C3.jpeg 4857B611-2C7C-48D8-94BF-6A7B4F40221B.jpeg

    How much longer will 45GAP ammo still be available? Target Sports only stocks 2 brands of ammo, and only Speer GD for JHP. Meanwhile the "dead" 40S&W has several times the variety available, and you can still at least get Gen 4 variants in all sizes. If 40S&W is dead, then 45GAP must be decomposing. Even so I'm itching to try it.

    GAP cases are more solidly built than ACP , because of the higher pressures in the shortened cartridge. It is unsafe to modify an ACP cartridge to fit GAP.

    By the way if anyone is curious Glock could have easily compensated the GAP models, mine function flawlessly.

    es350’s testing has shown that it can absolutely be done safely with 45 ACP brass manufactured by ATK (Speer, Fed, Blazer) with a Small Pistol Primer. The original worry, according to Speer’s own technical brief, was two-fold. Large pistol primers from ACP brass would raise pressures if data was substituted without adjustment. The secondary worry was that brass would bulge from the deep-seated bullets, because ACP brass is actually thicker (ie stronger) at the web. This bulge isn’t a safety issue and was never represented as such by Speer. It can be mitigated with bullet selection, COAL, and perhaps a Lee FCD.

    The jig would also have to address differences in the rim if 100% reliability was to be achieved. Still, the proposition of taking free SPP 45 ACP brass and converting it into unicorn GAP brass is very appealing to me (in case the caliber dies and we have to become wildcatters.)

    If I get around to it, I’ll section a piece of each from Speer and post a pic. The GAP isn’t stronger. It’s just different.

    I’m not claiming there is an over abundance of .45 loaded ammunition, but there is quite a variety out there. Gold Dot is available in 185 and 200. Winchester Ranger 230, MagTec and Buffalo Bore also offer a few.

    AmmoSeek shows 216 listings representing most major manufacturers.

    I don’t think it is going away anytime soon.
