Galactic collisions are very common in the Universe. Of course, the space and time scales for these collisions are extended. The Milky Way is presently gobbling up several smaller galaxies. The Magellanic Clouds (Large and Small) have streamers of stars merging with the Milky Way. There are several others some of which went unseen until they were able to be imaged from space in other wavelengths than visible light.

We see many mergings of galaxies in the universe. Take a good look at the images made by the Hubble Space Telescope and of the other space telescopes in non-visible wavelengths. You will notice many mergings. The gravitational effects are great and show up in the turbulence throughout such merging galaxies.

That "turbulence" also produces regions of intense new star formation. It isn't that individual stars within merging galaxies collide, but rather the vast areas of inter-stellar gas and dust within merging galaxies collide and heat up to eventually become new stellar nurseries. This isn't the only way new stars are formed, but a lot of new star formation results from galaxy collisions.
