If you can call it a problem, the Ruger lockwork makes getting a sweet trigger pull a near-impossibility. It can be improved, but only a little. It will never feel like a Smith & Wesson trigger. Then again, the GP will eat loads that will shake a Smith loose in no time. I can say that because I put loads thru my GP-100 (6-inch) that I would not let near my Smiths. The Rugers may not be as slick, but they are tough as a tank. If you want both, get a Freedom Arms for three times the price.
