I recently acquired a like new SS Mil-Spec in a gun trade. I've changed the finish to a brushed look, added some grips and hex screws I had in the parts box, blacked out the white dots and added an EGW drop-in bushing. I'll add a King's checkered hammer and Ed Brown thumb extended safety and call it good.
I now have about 500 rounds through it and I'm very pleased. The trigger still has some creep -- I'll have the gunsmith stone the sear when the hammer and thumb safety are replaced. Accuracy is very good and the tendency to throw the first round (hand cycled) out of the group seems to be going away as the round count climbs. It will put the remaining rounds in one big hole. Not as accurate as my SA's with Bar-Sto and Kart barrels, but plenty good for shooting inside 25 yars. Reliability has been almost 100% with 10 different mags and an assortment of factory and hand loads.
I traded straight across using a gun I had previously acquired for $300. I'll put $55 in the new hammer and thumb safety and another $40 to install them and smooth the trigger. At $400 invested, I'm feeling very good about the transaction.
Thanks for the responses. It's difficult to tell looking at the photo on SA's website whether the stainless finish is a " brushed", glossy, or other? How would you describe the finish? I'm glad to hear they're available.
