You will have to contact Glock for manufacturing data. Don't be surpirsed if they don't provide it.

Unfortunately, you can only convert a Glock 19 to .22 long rifle for cheap practice with a conversion slide and barrel, such as from Advantage Arms. Such kits are in extremely high demand and are very difficult to find.

While the .40 s&w, the .356 sig, and 10mm auto glocks can be downconverted, you can't go "up" from a 9mm base model by swapping out a converstion barrel. Conversion barrels are available from compaines such as as Lone Wolf, Storm Lake, and Bar-Sto.

.40 s&w, .356 sig, and 10mm glocks can be converted down to 9mm by swapping both the slide and the barrel. 9mm conversions also require 9mm magazines. .40 s&w and .356 sig can use the same magazines.

One further complication is that "Generation 4" model parts won't work with "Generation 3" model parts. Know what Generation of Glock you have before you buy conversion parts that may not fit.

100-400 USD or so depending on specifics

Assuming you mean a Browning Hi-Power.

In general, none. The Glock is available in more sizes and calibers, has less recoil in the same caliber, is as or more accurate and as or more reliable.

The manual safety of the Browning leads some people to conclude it is more safe, but the fact that it's single action leads some people to conclude it is less safe.

If the Browning fits your hand better, use it. If the Glock fits your hand better, use it.

no the magnum round is only for revolvers the correct round to use would be the .357 sig

No. 10mm is close to .40 cal, smaller than .50 cal.
