The patch sticking is chronic with the Crockett because there's a gap between the back of the barrel and the face of the breech plug. Just loves to grab standard small 32 caliber cleaning patches. The solution is fortunately easy: Use a bigger patch. If your patch is too small/short and the edge gets out into that gap, you're screwed/blued/tattooed in worst cases as it jams up tight and you just about have to dissolve the patch to break it free. Also helps to give a little clockwise twist to the cleaning rod just as you start to withdraw the patch/jag, both to make sure the jag is still tight to the rod, but also to help tighten the patch around the jag so it pulls free easier.
Fun little guns, but a little warty without some tuning such as that. Here's some more:
The barrel key rides right in your hand while carrying. Meanwhile the key is a little long and the sharp corners just love to dig flesh. Round the corners on the key and even shorten it slightly if necessary, and your hand will be lots happier.
You're right about the sights, and the fix will vary with individual eyes. For my eyes the fix was simple. I just used a point file to open the gap in the rear sight about 25%.
The lock on my Crockett and those of both my neighbors who own them proved a little tender, eventually starting to eat mainsprings. We did 14 extra laps around the email course with Traditions back them (a few years ago) trying to get fixes and never could get them to respond. We finally learned that they never looked at their email or some such excuse, but I understand they're better now. Back then the only solution for dealing with them was to pick up the phone. If you have any trouble at all, I'd still call first before expecting them to answer an email.
