barrels, mags, and recoil springs are interchangeable but there is some dimensional variance between generations and production years. Allegheny arms averaged a handful of reference pistols when making their barrels so they may be loose or tight. This 80x is about 1000 rounds in and pretty damn loose while the same barrel has zero slop in this clapped tf out cop surp 81. If your barrel is too tight, you can fudge the last bit by tapping the muzzle with a mallet while trying to lock the takedown lever.
