I was a SW fanboy from mid 90s to 2008.
I started out with a 4506-1 that I sent to the PC and they gave it a slick duty action.
At the original AstroHall Houston Gun show, my dad and I ran into a 4566 CQB and if I recall it was around 800-900 used. I did not have the money and my dad was going to buy it but I told him no.
I later found a 4563 CQB (SW CQB 45) and I sold my 4506-1 to pay for it.
When I got moved to Narcs in 98, I found a brand new heavily covered in dust 4516-2 for dirt cheap at another Houston Gun Show (my dad and I would go every year). My first depression of the mag release was a fail as the mag release spring rusted out over the years of just sitting in a gun display case and or humid environment. I also sent it to the PC for a duty action job. SW back then would prioritize LE guns and I would get them back in a few weeks.
My dad would find a Shorty45 at the Houston Gun Show and bought it.
Then one day, I am trolling through the local gun shops and low and behold to my amazement, in the glass cabinet was a DPA5906. I think I put it on layaway and worked off duty gigs to pay for it. The action on it was butter and it was a shooter. If there was any PC I should have kept, it was this one. you just dont see them anymore.
Here is the DPA5906 and I put Hogues on everything back then.
I ended up with a 945 (accurate beast), 845 (Smooth and accurate), 4566CQB, 4013TSW, 3953TSW, CS9DAO, 6906 I might be missing a couple.
I eventually sold them all when SW stop making parts, plus in 2008 we were finally allowed to carry 1911 style Single Action on duty.
