The TTI pads do not require tools to remove. I prefer they because of the variety of sizes to match some of my shorter magazines.

The 11 coil spring will work fine. The 13 is for 170mm.

I use TTI pads on all my SVI/STI mags. The size of the pad depends on the length of your magazine. I use the 7mm on the older 131mm mags for a total of 19 rounds with Grams internals. All of my 140mm mags pass the gauge with the 4G pads.

Older SVI mags are compatible with STI. Newer magazines are slightly different dimensions and do exactly as you described. My gunsmith made a slight modification to my frame so it would work with the newer mags (and the old ones). The way it was explained to me was the frame required modification, just modifying the mags would not work.

Try Harrison Custom. He makes a Novak cut sight for the Springfield that is .350. I noticed he also offers custom notches for some of his other sights. https://shop.harrisoncustom.com/hd-0045-rear-sights-for-novak-cut

I usually cover the tip of the punch with masking tape to prevent marring. On a Sig try driving the sight from right to left.

Definitely 10mm MP5. Shot quite a few rounds from one of those.

The Winchester 124 NATO load is also pretty hot. It approaches +p velocity and provides more gas to work the comp. I would try a box of that to see how it feels.

I would get the SVI spring. It is already fit to their follower. I have used the 10 coil springs, but if doing it again I would get the 13 coil and test them. If I didn't get the capacity and functioning I was looking for I would start trimming the springs. I hear people have had good luck with between 11 and 12 coils. Have not tested them myself.

I have used the SV ultra capacity (aluminum) followers in my older 9mm mags without a problem. I'm not sure if SV is still offering them for sale. I could not find them on the website last time I looked for them. I have also used the TTI followers without incident. I would buy either of them without hesitation.

The MSA Sordins with the gel cups are money well spent. I have been running a pair for over 8 years with only the occasional battery change. I also have a pair with integrated comm's that I use at work. Never had an issue with them at all. I was going through Peltors every 15-18 month before I made the switch.

Was never a big fan, but there is no denying he was a very talented musician. RIP

Try shooting a group with burning the first hand cycled round into the berm. If you still get the flyer, you can start looking at the ammo. If the flyer goes away, it probably has something to do with barrel fit.

I've never done this, but there is a tech tip on the uniquetek website on how to do this with hot glue. It's tip #10. http://www.uniquetek.com/site/696296/page/217691
