You can't shoot Sig226 under water. Glock you can. Seal Teams have been using Glocks for several years unit purchase. SIG are ok for law enforcement applications, not for tactical. SA pistols are quicker for trigger reset and more accurate for multiple targets and multiple firing. Shot both, issued both, Glock is better. XD is even better ... new strike fire H&K 9 wow. But Glock in the elements outperforms. The more badguys not using Glocks, the more I win.
...the bullet goes 3 feet under water with no power passed the first couple of inches (and I believe you need a new srping to do this anyways?)...This ONLY works when the gun is fully submerged in water and ALL the air is out, otherwise you can have some serious issues with it.
