Ive owned a Spartan in 45 for about 7 months and it is a great gun for the money. It is a deadly accurate pistol, mine will bench 5 shots at 20 yrd. into sub MOA (which is better than my Dads STI USPSA SIngle Stack Shot). It is a remarkably tight but slick slide to frame fit, feels like a custom really. I have around 8000 rounds thru it and its still tight. Great crisp trigger without creep. Ive used it in USPSA Single Stack all this year and love it. But as with all things there are a couple negatives, though they are minor.
The two bad things I encountered is: (1)- they will not reliably feed SWC. Before anyone says it I know a non-ramped barrel was designed for hardball. Over the years gunmakers have made the non-ramped barrel suitable for SWC. All Im saying is the non ramped barrel configuration in the spartan is not enhanced to feed SWC, at least mine wasn't. (2) The polymer mainspring housing. I dont like the feel of the checkering on it and the fact the spring retainer pin hole started to oblong under the tension. Luckily they are trivial and easily remedied, get the barrel ramp angle changed to feed SWC and buy a SS mainspring housing. (Both of which I did).
