I'm in the same boat as you. I sorely wanted one of these before the SP-01 Compacts came out, and ended up building up one of those when they came on the market.
I spent waaay too much on gun stuff in 2016 and 2017 and I want keep my purchases this year to a minimum, but I don't think I can pass one of these up after waiting for 3-4 years. Might have to purge a few Glocks out of my collection I never shoot to justify it.
