I did the slingshot mod to mine. I didn't bother with removing the magazine disconnect because it's not a defensive pistol for me, plus you need to order a bushing if I remember correctly.
I wanted to "get the hang of it" before I started shooting mine, and it was a royal pain. Every time, I had to use a punch and a soft mallet to get the slide stop pin out, and every time, I needed the mallet to get the pin back in upon reassembly.
But after putting just 300 rounds or so through the gun, stripping and reassembly got MUCH easier, to the point where I no longer need any tools.
Even after about 5000 rounds through mine I still need a mallet and punch to get everything back in and out. It did get easier, but it can be a pain.
