[G-man*]

I have about 500 rounds through a new glock 26 gen 5 that still jams with 115 grain Winchester ammo. When I shoot 147 grain, the gun doesnt jam. I know 115 isnt full powered ammo, but I didnt think it mattered with a Glock. I kinda have a sorta different impression of Glock now.

Does anyone else experience this problem? I heard the rsa is tight, but I shot a g43 with the same 115 grain ammo and not one malfunction.

Nope. Mine runs like a champ regardless of ammo.

Get someone else to shoot a few mags they it and see if it happens with them.

Just a tiptoe off the beaten path . . . My G30 has balked only on one load--my attempts to reload 200-grains SWCs. Had a very bad time going into battery no matter how I set the COL and adjusted the HP-38 powder throughout the recommended load range. Did some digging and found others had the same issue with SWCs. Dumped that style bullet and never looked back.

Try a truncated profile bullet instead of the swc. They are similar, but enough difference to make a difference.
Very similar profile to a Hornady XTP. Also, crimp has to be good. I bought a 45 Auto gauge for the plunk test, and found that I had to run the crimping operation separate from the seating. Maybe due to using mixed brass, and some would not chamber.
Ran the crimp separately and they all feed perfect in the G21.
