Is the gun for fun, or something else. I'm guessing a 17L is for fun.
Fun...I'd go with Daswson Precision Adjustable Rear with a 0.300 Tall front 0.100 wide fiber optic.
Business...same rear with a night sight/fo combo for the front. There are several options available, but it will need to be 0.300 tall.
I had the sevigny/warren setup on my Glock 34 and just switched to the dawson set up. There's still 0.025" clearnance so you can get a very quick sight picture, but for me it's a little more accurate than the 0.035" clearance with the sevigny set up.
Food for thought.
