I recently bought a 37 that had a broken stock from a local pawn shop for $150. The front sight was also gone. I cut the barrel down to 18.75, and installed the latest Choate plastic stock after fruitlessly looking for a wood one on the net. I already had a Choate plastic corn cob forend from an Ithaca long since traded, so I ended up with new plastic front and rear. I was at first kinda wanting wood, but once the Choate was installed, I've changed my mind. The current Choate fits me perfectly and comes with adjusting spacers as well. The gun now feels like it was made just for me. I took it to the range last weekend, without a front sight still, and it patterned great. Even without using a sight, it shot exactly where I was (hopefully) aiming. I can't wait to try slugs once I get the front sight on. The barrel chopping didn't seem to effect accuracy at all.
For the front sight, I bought a tritium Meprolight from Midway, which has since arrived and looks like the ticket for this gun. Now, to just find some time to install it.
