SP-01 mag springs
« on: January 03, 2019, 07:51:21 PM »
Seems like lots of people buy Wolff +10% springs right off the bat for their new SP-01 mags.
Can anyone tell me the correct part number and is it even necessary if you’re not getting nose diving, etc? This is for the standard 18 rounders.

Just saw CZC sells them. I’ll pick em up from there.

Just so the information is here for future use, I ordered Wolff 74271 +10% for the SP01 18 rounders. I got by for a bit without them but yesterdays match had some muddy bays and by the end of it I was having malfunctions with them and could tell the spring was not keeping up. Cleaning them obviously helped but the Mec-Gar 17 rounders ran fine and have a much stiffer spring.

Yeah I figured I’m just going to do it right out the gate. My last brand new SP-01 had nose dive issues with the mags from the very first time I bought the gun. It’s a cheap precaution IMO.

I assume this issue is mainly with fully loaded mags?  For PPC we only load 6 anyway.

But I have upgraded several other brand magazines with Wolff springs and wouldn't hesitate to recommend them.  They even make +power mag springs for my Model 52 which was built specifically for 5 round Bullseye shooting.  We machine out the side slots to take the 6th round for PPC and a heavier spring is a help.

In my first SP-01 I would just randomly get them throughout at no particular point. Gun would jam, look, rounds nose diving in mag. Some say that the OEM mag springs are weak so I figure $6 is an easy precaution.

Good to know - expect I will order a pack from Wolff in the near future.

Just installed the +10% power springs from CZC. Definitely noticeably more resistance when loading a mag vs OEM spring. I think they’re a great upgrade and certainly can only add to reliability as far as feeding.
