I have acquired a 3“ Detective Special in the 2nd gen pattern with thes extractor rod exposed. The F serial # dates it to 1974. Thoughts?

I'm interested in picking one of these up in .45 ACP, because I've got enough 9mm tactical pistols to last a lifetime.

I'm just not sure what variant I should be aiming for. I'm sure they're all going to have good triggers, and I have no particular preference over series 70 or 80. I own pistols that use both and it's not a deal breaker.

Seems like the Gold Cup Trophy can be had for a very reasonable prices used/like new (around $1,000). Is there any reason I should be aiming for a national match instead, or perhaps an older model?
