Been doing some youtubing for a good optic. My second handgun ever was the G34 MOS when it first came out and I'd put a Trijicon RMR on it. Cool, but nothing to wow over.
Been looking at two options going forward - the Trijicon SRO, or the Holosun 507C with the ACSS Vulcan reticle. Some very informative reviews out there. The Holosun is in stock at Tenda for the cheapest list price in Canada right now - about 40% cheaper than an SRO. In fact the only place in Canada (at least on Google) that has them in stock at all. No point in having this amazing new optic ready mean-machine without a good optic for a great price!
