We tried some 38 s&w today, was to girthy just like the dominions we tried. We have a short colt, but it doesn't plunk into the chamber, you need to push it in hard to have it fit, and need to ram it out after the fact. We are unsure on the type of firearm. It has no markings, no serial numbers. Well, it has a few markings, comparable to what you'd find on a enfield in certain spots.
