Taurus PT145 Magazine Springs(Para P14?)

[Jes]

I really like my PT145 but the last range session one of my magazines started having nosedive failures after about 75-80 rounds. This gun has approximately 600-700 total rounds without a problem until now. I have searched for aftermarket magazines and springs (Wolff) without any success.
However today I stumbled across a thread where someone used Para P14 magazines in their PT145. Wolff makes extra power springs for the Para P14 and Midway has them for $6.99 MidwayUSA - Wolff Magazine Spring Para-Ordnance P13, P-14 10% Extra Power

Look at the photo of the spring.

It is almost identical to the PT145 and PT24/7 springs. It seems to have 2 more fat coils and 1 fewer thin coil(top). Just a possible solution for the other PT145 owners out there.

I bought some P14 springs and fitted them to my 10rd PT145 mags and 12rd PT24/7 mag. They are definitely stiffer than the originals. They do help.

I started cutting one coil at a time and trying the mags for capacity and function.
The 10rd mags still function best with only 9rds but I discovered another problem while working on the spings. The mag release notches in the factory mags are cut about 1/32 too high. If I push up on the mags function was perfect even with my truncated cone hollow point handloads.

Anyone have a fix for the release notches on mags?
