I'm running a SWR HEMS II on a Glock 21 gen 4 w/ a lone wolf barrel.

Several issues of failure to return to battery and then it started stovepipe jams. Most of these occurred on the last round in the mag.

No issues while running can on a 1911 or HKs.

Looking for helpful advice to remedy.

Recoil spring assembly.  You need a new one.  How many rounds on yours now?

Yeah I'd start with that..FWIW I have the same set up HEMSII with G21 Gen 3 /Lone Wolf ..The only time I ever had the problems you descibe is when I tried to mount that can onto a G30

My thought was the RSA as well but I don't think I've even got 1k on it but that's a cheap part to try.

My 19 needed some break in time. No issues since. Rack the fuck out of it first is my advice before throwing parts at it.
