Hogue G10 checkered. Love em. Better than the stock E2's that came on it and way better than the plastic 226 grip....For me anyways, IMHO
+1 on Pachmayrs on the NP-22 clone.
I wonder how hard it would be to throw some G-10 on the HAAS and just make some custom grips...
Try the Hogue Alum's or their G-10 models. I have them on most of my Sig's now and they work great. Hogue will ship to Canada as well which is a bonus. They are pricey but still cheaper than the Sig alum. grips being offered up here and their shipping is quick.
Check out their web-site, although they don't have pictures for all their different models. Some of the G-10's have quite aggresive checkering and some are almost smooth so be careful when ordering. Don't ask how I found that out.
