I bought a lightning strike GR for a G17 from Brownells that I understand to be swappable for the stock M&P one. It came with a round spring guide rod, presumable sprung for a G17. I also bought a bunch of ISMI flat guide rods for Glocks, to play around with springing the M&P, and the darn flat spring doesnt fit the rod, its too tight.

There are a lot of glock guys on here, so is this normal? Do ISMI flat springs not fit some aftermarket rods?

Which ones specifically will work in the M&P with ISMI springs? Thansk for the help.

the ONLY part I know of that works is from TopGlock.Com



42279 Captive guide rod for models 17-22-24-31-34-35 $20.96



42282 Non Captive guide rod for models 17-22-24-31-34-35 $16.88



The flat wire springs require something special about the Rod.



Personally, I go with Wolff.
