Looks a lot like the Seecamp Colts and the Double Eagle with a bobbed hammer. OBVIOUSLY DA only.
Those Seecamps made by OTHER companies have a HORRIBLE trigger, trust me I have one. The 'real deal' Seecamps are supposed to work pretty well.
I thought the Double eagle was pretty functional design, weak point was the grip holding in the DA 'guts', if you dropped it and broke that grip you might have parts everywhere.
The old 'conversion' frames had a metal side plate that held everything in.
And wait is that a POLYMER fame???
