A recent question was posed by my sheriff whether we should stay with Glock and upgrade to gen 4 or go to the m&p. i say glock becuase of the customer service, warranty, ease of armoring and the tried and true Glock name. But, the m&p is a sweet shooting gun man. Only downfall I see is detail stripping this gun is a b$&ch! Looking for pros and cons vs. both. Thanks for you input.
