okay well this is my first uberti to own and have any experience with and yes I do reload been doin it for 22 years now but I do like the gun and I saw a video on youtube about a guy showin them spring kits from wolf springs he put in his gun so I wasn't sure about these springs. so anyway the hammer spring are they normaly stiff as this one is to me light and I saw where another guy sayin to keep bolt/trigger springs on hand as they he says break from time to time so is it better to just keep the factory springs in and do I need to buy a couple extras to keep around?
p.s. it does dent the primers very deeply even with the light hammer spring! or at lest light to me...
Well, without having the gun in hand there is no way I can tell you how stiff it is, can I? You could perhaps compare it to others like it. As I said, many shooters trade out the factory spring for a lighter, aftermarket spring. You may have one of those, there is no way for me to tell from here.
The question is, did it fire the primers, not how deep did it dent them. You can put some fresh primers in some empty brass and drop the hammer on them. As I said, many of these guns are tuned so they will only fire Federal primers. Seat a few Winchester primers in some empty brass and drop the hammer on them. If they fire, there is no need for a stiffer hammer spring. Just be aware that when you fire primers in empty cases the primers will back out and may make the cylinder difficult to rotate. Just fire one round at a time.
Yes, the trigger/bolt spring on these guns is subject to breakage, exactly as the one in my photo. To give you an idea, I probably put 4 or 5 thousand rounds through it after I bought it. No idea how many rounds before hand, but the gun was made in 1968. And further, I probably have close to a dozen single action revolvers chambered for 45 Colt. That is the only one that has broken the trigger/bolt spring yet. So yes, it does not hurt to have a spare on hand. Chances of you needing it will vary.
The one other spring that often fails in these guns is the hand spring. Normally it is a leaf spring pressed into a slot in the hand. These photos should give you an idea what it looks like.
As I said, many of the newer guns do not have a leaf spring like that for the hand, instead they have a coil spring and plunger in one of the frame screw holes, Ruger style. If so, that spring will last forever. If you have one of the traditional leaf springs, you might want to keep a spare on hand.
