SpanishGlock 19 vs 45 vs 47 Gen5 MOS: Which Size for CQB Sidearm?
Quick answer: On the VFC Gen5 MOS listings, pick the G19 for the shorter slide, the G45 if you want the compact-slide, longer-grip shape, or the G47 for the full-size named pistol. All three were in stock on 3 November 2026. Check the product page before you order. Do not assume a Gen3/Gen4 G19 magazine fits a Gen5 MOS.
OEM choice, if you have not made it: Tokyo Marui vs VFC/Umarex Gen5 MOS. Parent: Gen5 MOS Buyer's Guide. Magazines and gas: First Gen5 MOS Loadout.
What the three listings are for
The size words below follow the product pages, including their real-steel notes. They are not holster measurements.
| Listing | What the page says | Who it is for |
|---|---|---|
| G19 Gen5 MOS | Compact MOS. Metal slide engraved "Glock 19 Gen5". Four optic plates named on the listing. | A shorter slide on the belt. |
| G45 Gen5 MOS | The page calls the real-steel G45 a compact slide with a full-size frame. The airsoft listing includes the MOS and four optic plates. | Compact slide length with a longer grip. |
| G47 Gen5 MOS | Full-metal slide cut for the MOS, with four optics plates named on the listing. The real-steel note describes a G17-length slide. | The full-size named MOS, if that slide length is what you want. |
A G19 holster is not automatically a G45 or G47 holster. Check the holster maker's chart.
Pick the slide length first. Then buy the magazine that names that pistol.
When MOS is the wrong extra
- You will never mount a red dot. An iron-sight Gen5, when its page shows stock, skips plates you will not use.
- You already own a red dot. Stay on an MOS listing, and match the plate to the optic footprint named on that pistol page.
Magazines, by what the listing names
- The 22rd VFC magazine title names Glock G17 Gen5 and G45. Do not buy it for a G19 Gen5 MOS or a G47 from this page. The title does not name those two.
- The dedicated VFC 20rd magazine for Glock 19 Gen5 had no inventory on 3 November 2026. Check that product page before you treat it as available.
- The other VFC G19 20rd magazine says it suits G19 Gen3/Gen4. That is not a Gen5 MOS spare.
FAQ
- G19 or G45 for a CQB sidearm?
- G19 if the shorter slide is the point. G45 if you want that shorter slide with the longer grip the listing describes.
- Does the G17 Gen5 / G45 magazine fit a G19 Gen5 MOS?
- The 22rd listing does not name G19 Gen5. Use a magazine that names the G19 Gen5, or wait until that page shows stock.
- Still choosing Tokyo Marui or VFC?
- Read Tokyo Marui vs VFC/Umarex Gen5 MOS first.
