Special “long throat” G20. They couldn’t , wouldn’t, chamber in any standard .45 barrels. My throating had “freebore” to the point it’s almost .45 Schofield length before the slug engages rifling and starts building pressure. Actually I accidentally took the throating tool deeper than I intended. But on a $50 barrel I thought I’d try it anyway. It works great and has conventional rifling, not polygonal. Remember, you’re not supposed to shoot lead through factory Glock barrels.

Not that I’d consider duplicating the exercise, it’s just interesting.

The 300’s functioned in the rubber gun fine. Good case support, no bulges, but I was running a hefty #26 spring and chambered brake too. Never intended a steady diet of them, just proof of concept. Velocity is classified, but you’d be pleased. lol

To me recoil is easier than the same gun in .40 or even a smaller one with hot 9mm. The .45 is more of a push than a slap. Even the teeny P380 “stings” a bit. But we are talking 10 oz., and a 16 oz. .45 ACP. I like the 155-170 gr. on the pocket big bores in .40, the 185 does seem to recoil less in .45.

It really depends on what the gun likes. Hard to limp wrist a 230 gr. ball load!
