Maybe that's the secret - clean sparingly...
Runs as reliably as my HKs but until the 500 rd mark - couldn't shoot w them accuracy wise. Just my .02
I couldn't ever leave my weapons dirty, I'm the anal retentive that field strips my XDs at the range and clean it and a light coat of oil while its still warm. I'm inclined ta say it's probably either a spring(return) or a light grip.
