TRT Tactical +3 P229-1 Mag Extension

2830 1
Has anybody ever used the TRT +3 P229-1 Mag Extensions.
That will make a P229-1 9mm mag hold 18 rounds & one in the chamber.
Sound great for a HD P229 with 19 rounds. Reliability ?
I know & have Meg-Gar +2 mags.
Inquiring mind wants to know.

FLASIG, I can't speak of their performance, but considering the +2 Mec-Gar units, in the majority of cases, you are using the same magazine spring. There have been complaints previously here, regarding failures of slides to lock open with empty magazines. I can see having to replace magazine springs more often with the increased capacity.
