I was looking for a Double-Star or other cheap 1911 frame to build a lower for a .22 conversion kit top that I've had for a few years and came across a Les Baer frame in the white at the gun show last weekend. He was asking $500 but after my fourth tip by looking at it, he made me an offer for $350 and I took it. I have all the parts for the build so I installed the grip bushings, then had to fit the adjustable trigger. The fitting required taking several .001 off op and bottom to allow it to freely pass through with minimal tolerence. Once the trigger was installed, the mag release goes it, it required a tiny polish and re-blue to smoothly operate. The ejector came next. It required some polishing as well on the posts and, once set, I used a 1/16" left-twist drill to make the cut in the post to allow the pin to fit. I found left-twist drill bits at Harbor Freight. The reasoning behind the left-twist is that it pulls the posts downward as it drills ( a right twist tends to push the post away, making a bad fit). The sear and dis-connect went in next and required no fitting but I did smooth the contact surfaces with a soft-stone. The hammer spring strut pin required some filing on the pin to allow it to pass between the frame opening on the rounded commander hammer I chose. Once the hammer was installed, the main spring and a Pachmyer hammer-spring housing were installed and pined with the hammer down to allow me to fit the ambidextrous thumb safety. Fitting a thumb safety is a painstakingly slow process. I am awaiting delivery of a staking tool from Midway before installing the plunger tube., it should arrive by the weekend. I am still having some issues with the grip safety fitting that will require some stoning and a refinish but the frame contour is a perfect fit. The trigger breaks crisply at about 3 pounds with no creep and the thumb safety positively engages and releases without firing the weapon. If you remove even a tiny bit too much from the safety, a 1911 will fire when the hammer is dropped. I have a nice set of stag grips for it and an extended belled magazine well that attaches to the lower grip bushings. I have not decided what length I will cut the frame yet, waiting to see how it balances with a full magazine and the top installed.
