They were originally a Croatian HS2000 pistol. Springfield was so impressed that they wanted to put their name on it.
You can get decent used ones for$5-600.
They are super. Has a grip safety like the 1911. Accurate too. I regularly ring the 100 yd gongs with them. There are some after market parts you can get from Brownells. Best upgrade is the short reset trigger. After upgrades, my trigger is a short, smooth 2.5 #s.
I do like it way better than my Glock even tho Glock has way more upgrade options.
Only downside is that the extractor cannot be bought in Canada and if that ever goes, you gotta send the gun back to Springfield for service. But, the extractor looks very beefy so it likely will last if you don't use steel casings?
