mikemyers, I have enjoyed your Model 52 discussions. As I have a handful of 39's, 52's and 952's... I have a knee-jerk reaction to this last post of yours above.
My experiences are my own, so yours might be different, however...
39's are fantastic, lovable, affordable and totally enjoyable pistols, but you won't find one that will impress you as a target shooter if you have put in this much quality time with a 52. The fitment won't meet the ability of a 52, the trigger is nowhere near what you have enjoyed with a 52 and the sights aren't in the same class.
If you had put in 5 years of dry fire and weekly sessions of hundreds of rounds with a 39 or 39-2 and then you bought a 52 for the first time, THAT would be an awakening for sure! Don't let my opinion keep you from buying a great 39, but it is no target pistol. With 52 experience and a mind and drive for Bullseye style shooting, a 39 is going to disappoint you.
As for a 952, I would make two key points-- first is that it isn't fair to blame collectors entirely for pricing these (long discontinued) guns out of an affordable price range, the fact is that the original price was over $2,000. So much like the 52-2 that now sells for $1200-$1400, those were $900 guns in 1993, the last year they were offered.
My second point... 952's are amazing pistols, but shooting them isn't much like shooting a 52 in my opinion. The 9mm runs basically twice the pressure of the .38 Wadcutter and the loads you run in 9mm are, by and large, not as inherently capable as a hollow base soft swaged .38 Wadcutter.
Can you match or exceed a 52 target with a 952? Maybe, but if you have years of 52 experience, you won't do it quickly. And yep, you'll spend thousands.
Now I love my Performance Center guns and especially my 952's, but if you are a long time Model 52 guy, I'm not sure a 952 would please you at two to three times the money.
