I have shot them both and preferred the sig. I have a sig on order and should arrive Monday. I beleive Parabellum in avon has the sig available for rent. I would call and make sure but I thought i saw it there. The sig fit me better and gives me the ability to change. I plan on getting the compact and sub compact grips. I can go small with 12 rounds or bigger with 15. I say the most important thing is which you shoot better. Both are good guns. Both are short reset. Trigger edge goes to sig not as spongy. Modularity goes to sig. Both are reliable. Cheaper mags and more aftermarket parts goes to glock.
