    Quick summary of the Pros/Cons for the Glock 20C:

    Pros:
    -Reliable (not a single failure to date)
    -Accurate (more accurate than 99% of the shooters that own one)
    -Durable (10mm Glocks seem to do better than their competition [EAA/1911/ect...] in handling the 10mm wear)
    -Easy to maintain
    -TONS of aftermarket support
    -15+1 capacity
    -Glock's customer service is great
    -Durable finish
    -Cheap replacement parts, should you ever need them
    -Low Bore Axis resulting in a relatively soft shooting gun
    -Easily modified to fit the shooters' preferences
    -Requires very little cleaning/lubrication to run reliably
    -Muzzle flip and perceived recoil are minimized vs the standard G20 allowing for faster follow up shots


    Cons:
    -The C model is much louder
    -The ported barrel may make your front sight turn black (mine doesn't seem to but I've seen others that do it after 2 or 3 rounds)
    -The ported barrel causes a decrease in muzzle velocity
    -The grip is large and may be too large for some shooters to grip properly

    Here's a video comparing with some shooting and a comparison to my Gen4 G20:

    It is unfortunate that Glock does not make an SF model 20 with a ported barrel/slide.

    How much velocity is lost on average from a 20C verses a 20?

    Nice review. I've been enjoying the 20C for 12 years now. Combine it an aftermarket barrel of your choice and a large quantity of Star brass, and reloading is straight forward and downright fun with this pistol.
    Cheers!

    Hmmm.....I have a 20 C and an extra unported barrel, sounds like an interesting project when it gets warmer.

    Nice, love my 20SF. Only thing I did was drop in a Wolf 22lb spring and guide rod combo. I probably have around 1600 through it with zero malfunctions, all reloads at real 10mm levels. Oh and I run a Lone Wolf stock length barrel in it about 75% of the time.

    It really depends on the round and spring weight. 50-150fps is a good general figure though depending on the variables.

    Just got back from the range with results for both ported and non-ported Glock barrels for the 17 (C) and 20 (C). I have Glock non-ported barrels for both of my C models.

    For the 10mm I used a light target load of 5.8 grs. of 231 with a Ranier 155gr. FP, loaded to 1.250", WLP primer.

    Non-ported-Ave: 939 FPS ES:43 SD:13
    Ported-Ave: 895 FPS ES: 65 SD: 20

    The 10mm Heavy Load is 10.7 grs. Blue Dot with a 180 gr. Hornady XTP, Loaded to 1.260" WLP primer.

    Non-ported-AVE: 1242 ES:38 SD: 13
    Ported-AVE: 1213 ES: 73 SD: 20

    For the 17 comparison I used Winchester white box, 115 gr. fmj's.

    Non-ported-AVE:1152 ES:53 SD:18
    Ported-AVE:1144 ES:61 SD:19

    Today's temp, about 38 degrees.

    In summary, the velocity differences between the 10mm non-ported and ported barrels were 44 FPS for my light load and 29 FPS for my heavy load.

    For the 9mm, it was just 9 fps.

    Hope this helps.
