Glock 19 vs Sig P365 vs S&W M&P — Which Should I Buy?
The Glock 19 is the best all-around choice with unmatched reliability and aftermarket support. The Sig P365 is the best option if concealability is your top priority — it holds 10 to 15 rounds in a micro-compact package. The S&W M&P 2.0 Compact has the best factory trigger and ergonomics of the three. Your hand size and primary use case should drive the decision.
Why It Matters
These three represent the top tier of the modern handgun market, and each excels in a different area. Buying the wrong one for your intended use means either carrying a gun that is too large to conceal comfortably or shooting one that is too small to shoot well at the range. Understanding the strengths of each helps you pick the one that fits your life.
