Man... I don't like the buy-in price, cost of replacement parts (and few channels to obtain them) or the complexity - compared to a 1911 or GLOCK but... The H&K P30 seems to be the only pistol manufacturer struggling with Quality issues right now. Maybe they are not increasing manufacturing capacity and running three shifts... Just doing what they do best and let the demand (and cost) rise to maintain their profit. Whatever the truth may be its working/I'm convinced.
Hands down P30.
If anyone thinks well of the P226 may I strongly suggest that you give it a try, too. They are oh, so smooth and I, too, am very accurate with one. Add the SRT trigger to a Mk25 and I would be very content.
