Now thinking about it. I only assumed it had choke threads. I just found out that my dad got the gun 25 YEARS AGO!!! Maybe it wouldn't have choke threads on an older model like that. The model 28 is discontinued now I think, so I question whether today's BPS barrell will fit it. Also, my uncle took it to a professional to get cut. Whether it was a gunsmith not I don't know. It doesn't look bad. I didn't notice the cutting, and probably wouldn't have, if I wasn't told that it was cut. Wouldn't this aslo make the barrell less accurate?
