Why does everyone pass on models in stock for the elusive mos. I have a few Glocks with optics and the only one with mos was a pita. Needed constant work and an aftermarket plate to solve the issues. All the milled ones were perfect.
There were lots of 17s for sale yesterday. The mos is a mounting system that is half assed at best and you pay more for. I dont get it. If you want a Glock then forget mos and buy any Glock you can find. There are probably like 100 left for sale in Canada over then next few days.
If you are desperately looking for an optic ready pistol because you cannot find anything then buy this. Mounting is better and the gun can be converted to other calibers, frames and slides. Lots of support and you can build new guns in Canada after the ban. https://store.prophetriver.com/sig-...ts-mod-poly-x-grip-320xf-320xf-9-bxr3p-r2-10/
If you want a Glock with an optic you cannot afford to wait anymore. Buy a Glock in stock if you can and have the slide milled. They sit lower, mount better and you still have a chance to can get them.
I haven't got my mos yet. Just happened to be instock at the time of a bit of panic buying. I'd suggest this as well or get a seperate slide milled. There is also C&H plates available. Or even the gen3s cause even the poly80 rmr cut slides will fit. Your going to most likely be changing the sights out so standard won't matter in the end if your going with a optic.
