I normally don't pay much attention to RATS as I can't/don't shoot Rugers worth spit. Also unless I'm just being snarky, I try not to drop in some crass meaningless drivel. Unless I'm really bored. BUTT:
Doug.38 mentions SAAifying the action on his Ruger(s). WARNING WILL ROBINSON .... WARNING .... WARNING. There are several ways to do this. Some lustrum ago, the most common method was to add a "half cock" by welding and cutting an additional ledge in the hammer. Half Cock. Then Remove the Transfer Bar and weld up the striker portion of the hammer. Neat. Simple. A WIDOW MAKER. The "Half Cock" was not a "notch" is was/can be just a LEDGE. A ledge just like FULL COCK. Think "short stroke." So when on half cock, loading, were one to touch the trigger, the hammer would/will fall .... BANG!! DO NOT entrust your Ruger to someone whom uses this method. EVER.
The Hammer needs welded up and real actual notches cut. NOT ledges .... NOTCHES. Then the trigger need reshaped to fit the new notches. Weld up the striker of the hammer and presto changeo >> a Coltized Ruger. One just might find, it much quicker, easier, and cheaper to buy a brandy new GW II by Pietta (I really like Stainless) and have ready access to OEM parts should repair be necessary??
Serious Thought and Research is NECESSARY
