Folks,
An e-mail to ISMI gun springs obtained some dimensional information on their line of Glock flat woven recoil springs that look very similar to the SP-01 design.
Mark Cosat of ISMI reports their spring's I.D. is 0.255" (SP-01 is about 0.210") and their spring's O.D. is 0.415" (SP-01 is 0.378")
The O.D. is a bit larger than the SP-01's spring. I'm worried it may interfere with the larger barrel diameter of the SP-01. However we do know that Wolff springs work fine. If the O.D. of a Wolff spring is around 0.410", I'd say we're in business.
Anyone know the O.D. of a Wolff spring?
