I have personally measured the grip of a Glock 19 gen 3 and a gen 4 with a micrometer. The difference is minuscule, and not even slightly noticeable.

Even with the change out backstraps?

Robar does great work but I have to agree with those who said look at a 19Gen4 instead. The naked backstrap (and trigger pull) is 2mm shorter than the Gen3 and that makes a big difference. If you add the medium backstrap it's the same as the Gen3 and the large strap makes it 2mm larger.

I just bought a 23Gen4 and looked hard at the Gen3 but loved the feel of the Gen4 with no strap. When I put on the medium strap it feels like my 22Gen2 so I have flexibility. Can't decide which way to go but like having the choice.

I would think you'd come out ahead buying a Gen4 and selling your Gen3 instead of shipping it off to Robar and the cost of the conversion. The only down side is the reliability issues of some 19Gen4s. Glock is still slow to fix this problem completely but it seems better with recent guns.

Most shooters go and have a grip reduction job to aid in shooting (or because they like the look).
I did a lot of investigation as decided to go with Ben at Boresight Solutions in Miami Florida. Ben is busy and you can expect to leave your lower for a month or two. But the work and the wait is well worth it.
I shoot and compete in Steel Competition and one of my guns is a Boresight Solutions modified G17 Gen3. It is a 2005 model and I jet never felt comfortable shooting it so it sat in the safe (have smaller hands and had hand surgery so the big grip was uncomfortable).

I meet with Ben and after going throughout my needs, we came up with the following:

Remove and reshape the back of the grip, remove the finger groves on the front of the grip, re-stipple the entire grip 360 degrees. I also had the finger guard rounded, and an upper cut in the rear to accommodate a high grip (use to 1911 grips). But it did not stop there, I had the bottom cut to accommodate G19 mag's and beveled for quick reloads. A finishing touch of stippling on the left from strap where my left hand thumb goes and done.
