Mykeal and Hawg!
I just got done buying two Remingtons to add to my pile. They are my fourth and fifth ones if you don't count the ones I no longer live with.
The most recent one is a clunker that needs a good bit of work. Four inch barrel and hinged cylinder pin was added by a previous owner who did not do justice to the work.
The gent who sold it to me did not do the work so he is innocent of any wrongdoing.
I am accumulating pistols far more quickly than I even imagined I would. Every time I see a photo of one, I want it. Which is why you guys are putting me in the poor house.
For TX,
I have used Pietta parts for ASM pistols with a bit of modification as Mykeal says. But I give a nod to Doc Law who needs a custom spring. I have never had to replace a spring on an ASM 1860.
On the other hand.....you are hooked now. You will be adding pistols to your collection and you will find that not being able to shoot a pistol, or wanting to limit the use of the pistol because parts are hard to come by is not going to be a major deal. I have about six pistols I don't shoot any more but I would not part with them for love nor money.
.36 Sheriff's model in Brass because it has a loose arbor from my only ever chain fire.
.1960 NMA from Belgium, because it is too nice
That Brass frame ASM 1860 in .44 because it is about my sixth 1860 and I just don't shoot it.
Colt Second Gen 1860 with fluted cylinder, also because it is too nice.
I used to take three or four pistols along to the field and try to shoot them evenly but I found that I was not learning anything. The last couple times I have only taken two pistols. I shoot one primarily, only taking the second one as a shooter if the primary craps out.
