I want a Rohm Trainer pistol, but as I can't find one I would like a well built, heavy co2 1911. I suspect the pellet firing A1 version is the best for this, but the Sig Sauer Max thingy looks good except for the stick mag. The WTP pre-ruined version doesn't appeal as I tend to scratch them myself. I did breifly have a tangflioliolio blowback a few years back, but the fit and finish were sloppy with lots of movement to the barrel/slide etc.

What am I missing?
