Test Gun: Sig P229, S&W Shield. Barrel length: 3.9 inches, 3.1 inches. Ammunition: Winchester .40 S&W 165gr "T" Series Test media: 10% Clear Ballistics Gel. Distance: 10 feet. Chronograph: Caldwell Ballistic Precision Chronograph G2. Five shot velocity average: 1151, 1093fps Gel Temperature 70 degrees. This is one snappy round out of the M&P Shield but quite a bit more manageable out of the Sig. With the Sig P229, I got an average five-shot velocity of 1151fps with a high of 1156fps and a low of 1147fps. 
In the Shield, the average was 1093fps with a high of 1105fps and a low of 1086fps. 
Round one in the bare gel had a velocity of 1151fps and penetrated to 15 inches. It had a recovered .64 inches and a weight of 144.1 grains. Round two hit at 1158fps, penetrated to 14 inches, expanded to .63 inches, and a recovered weight of 145.4 grains. 
Performance in Heavy clothing was very well with the first round having a velocity of 1138fps and expanded to .66 inches with a recovered weight of 150.6 grains. Round two had a velocity of 1141fps, expanded to .64 inches and a recovered weight of 153 grains. Both rounds penetrated to 15 inches. 
Out of the Shield, the first round in the bare gel had a velocity of 1095fps and penetrated to 15 inches with an expansion of .66 inches. Recovered weight was 144.2 grains. Round two's velocity was 1097fps with a penetration 14.5 inches. Recovered diameter was .67 inches and a weight of 144.7 grains.

| Thank you. Good info there. |
To compel a man to subsidize with his taxes the propagation of ideas which he disbelieves and abhors is sinful and tyrannical.

| 180 is the way to go in 40. It is less snappy due to lower slide velocity. |
