Glock 21SF and laser sights

[giggitygiggity]

I am looking to get either a laser or laser/light combo for a Glock 21SF. What are my options? What lasers should I look at and which ones should I avoid? I am particularly interested in the Streamlight and Surefire laser/light combos. Basically, I'm looking for a good laser that will hold zero well on a .45. I'd prefer if it cost $350 or below. Please let me know what you recommend. Right now, the Streamlight seems like it is basically the same as the Surefire, but at a fraction of the price. Thanks.

I like my Crimson Trace LG-617 from a quality standpoint, but overall I'm starting to like laser sights in general less and less.

I want one more because I intend to get a suppressor for mine which would block the traditional sights

I have a Sig STL900L on my 21SF. Love it...
