In my opinion, I'd stay away from all poylmer guns (except the XD). All the ones that I have seen (Glock, H&K, Walthers) that have had more than 10000 rounds through them seem to have lots of problems. Be it springs, or the frame rails, (or at worst) I've seen some of them blow up. (Two Glocks, one Walther, and one HK). Steel guns are the best in my opinion. I prefer 1911's and obviously the CZ's as the two best. If you get a Walther, I'd say get rid of it before you reach 10000 rounds. I hope this helps.
I don't think durability is necessarily the issue with plastic-framed (and don't kid yourself, it is plastic) pistols, the two things that I always find fault with is that they have more recoil because they have less mass and they have crummy trigger pulls. (And if you read in a gun magazine that plastic frames "absorb" recoil, I suggest using that gun magazine as toilet paper for your pet - simple physics rules that one out, the reason the Glock doesn't have as much perceived recoil as some metal-framed guns is because of the grip angle.)
Yes, yes, I know, you can get the super-whizzbang trigger connector for your Glock, and someone won the IPSC Standard Division World Shoot with one (once), but I always wondered how much effort that took. A hell of a lot, I suspect.
I used to shoot in competitions with Armando Valdez, who at the time was considered to be the best Glock shooter in the country (used a Glock 24) and as soon as the STI guns came out, it was all over for him, really.
The trigger pull on some of these guns is good enough for government work, but they weren't designed with target shooting in mind.
I know tons of people use Glocks for target shooting and do well with them, but does that mean the gun is the best choice? After all, I've seen Jerry Miculek kick serious ass with a revolver, going up against guys with customised 1911s.
The best trigger pulls on plastic-framed guns are the ones with metal triggers, like the SIG Pro (which also has a metal locking insert that the slide runs on). I was shooting a S&W M&P the other day, and I got seven holes in the target at 25m in a pretty tidy group, with three fliers - because of the trigger pull.
If you like mastering mushy trigger pulls, by all means buy one.
